What Causes Abnormal Noises When a Car Turns?

[AryaMarie]

When a car makes abnormal noises while turning, the possible reasons are as follows: 1. Friction between plastic components. 2. Friction between the steering column and the floor mat. 3. Malfunction of the clock spring inside the steering wheel. 4. Aging or excessive play in the steering tie rod ball joint. 5. Excessive gear clearance in the steering gear. Below is more information about the car: 1. The steering wheel is composed of various plastic parts. If the gaps are too small, abnormal noises may occur, especially in new cars, which usually resolve after a break-in period. 2. If the noise persists after the break-in period, try reinstalling the steering wheel. If the floor mat is too large and comes into direct contact with the steering column, friction will occur when the steering column rotates, producing noise. This is a common issue and can be resolved by adjusting or replacing the floor mat. 3. If the noise is caused by a broken clock spring or a loose clock spring connector, replacing the clock spring or securing the connector will fix the issue. 4. If the driver hears a clunking sound when turning the steering wheel while stationary or at low speeds, or feels vibration or knocking in the steering wheel, or if tire noise increases while driving, it may indicate a faulty thrust bearing. The thrust bearing connects the car body and the shock absorber to prevent direct friction and consists of components such as a dust cover, raceway, and ball bearings. It is located at the top of the shock absorber assembly and typically has a lifespan of 40,000 to 60,000 kilometers. Once it reaches its service life, it is recommended that the owner have it inspected.

When a car makes abnormal noises while turning, the issue could stem from several areas. The most common culprit is a damaged outer CV joint—the metal housing connecting the drive shaft to the wheel. When worn, it produces a metallic clunking sound during turns, especially noticeable during sharp maneuvers. Steering system problems are also frequent, such as increased gear play in the steering box or loose tie rod ends, resulting in a thudding noise when turning. The suspension system warrants inspection too; for instance, aged or cracked stabilizer bar bushings can cause squeaky rubber friction during turns. Improperly installed brake pads may shift and scrape against the rotor, emitting a high-pitched grinding sound. I recommend first identifying the noise type: metallic clunks point to CV joints, rubber squeaks suggest suspension bushings, and thuds indicate steering components. These are critical safety-related parts—don’t delay repairs.

I've encountered many vehicles with turning noises, mostly caused by aging chassis components. Issues like worn CV joints are particularly common—when the dust boot tears and lets in grit, the CV joint core gets grooved, resulting in clicking sounds during turns. Loose ball joints in suspension arms can also cause this; the last car I repaired had excessive play in the arm's ball joint, making a drum-like thumping noise when turning. Another scenario is stuck brake caliper guide pins, where the brake pads don't retract during turns, creating a harsh metal grinding sound. These faults often follow patterns: metallic noises usually point to steering or CV joint issues, while rubbery sounds indicate aged bushings. A simple DIY check involves crouching to inspect CV joint boots for tears and shaking the tire to check for play. Safety comes first—unusual noises are often early warning signs.

Don't ignore turning noises—they directly impact driving safety. A failed CV joint could suddenly lock during sharp turns, which is extremely dangerous. Loose tie rods are even scarier, causing the steering wheel to abruptly become heavy or loose. When hearing unusual sounds, I recommend immediately checking three things: whether the steering wheel vibrates when turning, if the noise comes from one side or both, and if it worsens during uphill turns. After parking, inspect tire wear for evenness and check for wheel hub deformation. Most importantly, avoid high-speed cornering and get a professional inspection ASAP. Repairs must be thorough—for example, replacing a CV joint requires changing the boot too, as partial fixes may fail within three months. Though chassis issues seem minor, safety is paramount.

Last week my car squeaked when turning, and later I found out it was due to cracked bushings on the lower control arm. Rubber parts deteriorate over time, and cars over five years old are prone to such issues. The mechanic explained that once the bushings crack, metal rubs directly against metal, causing noise when turning. Here’s a useful tip: if it squeaks when turning right, check the left wheel’s CV joint; if it squeaks when turning left, inspect the right wheel’s CV joint. This is because the outer wheel bears more force during a turn, making issues more noticeable. Now that it’s hot, rubber softens, and noises become more obvious. Minor issues like clearing small stones stuck in tire treads can be DIY, but for steering system problems, it’s best to consult a professional. Regular maintenance should include checking for cracks in chassis rubber components—early replacement saves money.

Turning noises often involve the chassis linkage system. The suspension, steering, and drivetrain systems work together, and any issue in these systems can cause abnormal sounds. In the suspension system, leaking shock absorbers can cause spring friction noises; in the steering system, worn steering knuckles or steering gear can produce clicking sounds; in the drivetrain, damaged CV joints are the most typical, creating a metal grinding noise. These components all bear lateral pressure during turns. There's also a hidden issue: worn wheel bearings can produce a humming noise when the load increases during turns. I've handled cases where uneven tire wear caused noise, as incorrect wheel alignment made the tire sides rub during turns, producing a sandpaper-like friction sound. It's best to note the vehicle speed and turning angle when the noise occurs for more accurate diagnosis.
